“…Antimony sulfide (Sb 2 S 3 ) has attracted tremendous attentions for advanced energy storage due to its high theoretical storage capacity (~ 947 mAh g −1 ), suitable electrode potential, and low cost [ 1 ]. Nevertheless, the practical application of Sb 2 S 3 suffers from poor conductivity, weak structural stability, lower initial Coulombic efficiency (ICE), and “shuttling effect” of polysulfide [ 2 , 3 ]. In order to tackle these key problems, multifarious ways have been proposed, such as combining with highly conductive carbonaceous materials [ 4 , 5 ], designing greatly stable structures [ 6 , 7 ], building interfacial bonds [ 8 ], and introducing doping heteroatoms [ 9 ].…”

Highlights The chemical process of local oxidation–partial reduction–deep coupling for stibnite reduction of carbon dots (CDs) is revealed by in-situ high-temperature X-ray diffraction. Sb2S3@xCDs anode delivers high initial coulombic efficiency in lithium ion batteries (85.2%) and sodium ion batteries (82.9%), respectively. C–S bond influenced by oxygen-rich carbon matrix can restrain the conversion of sulfur to sulfite, well confirmed by X-ray photoelectron spectroscopy characterization of solid electrolyte interphase layers helped with density functional theory calculations. CDs-induced Sb–O–C bond is proved to effectively regulate the interfacial electronic structure. Abstract The application of Sb2S3 with marvelous theoretical capacity for alkali metal-ion batteries is seriously limited by its poor electrical conductivity and low initial coulombic efficiency (ICE). In this work, natural stibnite modified by carbon dots (Sb2S3@xCDs) is elaborately designed with high ICE. Greatly, chemical processes of local oxidation–partial reduction–deep coupling for stibnite reduction of CDs are clearly demonstrated, confirmed with in situ high-temperature X-ray diffraction. More impressively, the ICE for lithium-ion batteries (LIBs) is enhanced to 85%, through the effect of oxygen-rich carbon matrix on C–S bonds which inhibit the conversion of sulfur to sulfite, well supported by X-ray photoelectron spectroscopy characterization of solid electrolyte interphase layers helped with density functional theory calculations. Not than less, it is found that Sb–O–C bonds existed in the interface effectively promote the electronic conductivity and expedite ion transmission by reducing the bandgap and restraining the slip of the dislocation. As a result, the optimal sample delivers a tremendous reversible capacity of 660 mAh g−1 in LIBs at a high current rate of 5 A g−1. This work provides a new methodology for enhancing the electrochemical energy storage performance of metal sulfides, especially for improving the ICE.

“…The combination of Sb 2 S 3 with graphene can provide excellent Na + energy storage properties. Therefore, many composites have been designed in recent years, such as Sb 2 S 3 /RGO (RGO = reduced graphene oxide) ( Yu et al, 2013 ; Wen et al, 2019 ), Sn@Sb 2 S 3 -RGO (tin assisted Sb 2 S 3 decorated on RGO) ( Deng et al, 2018 ), S-RGO/Sb 2 S 3 (sulfur-doped RGO-based composite with Sb 2 S 3 ) ( Zhou X. et al, 2020 ), and Sb 2 S 3 /N-C/RGO (Sb 2 S 3 @nitrogen-doped carbon decorated on RGO) ( Zhan et al, 2021 ), to improve the storage properties of SIBs.…”

Recently, sodium-ion batteries (SIBs) have attracted extensive attention as potential alternatives to lithium-ion batteries (LIBs) due to the abundance, even distribution, low cost, and environmentally friendly nature of sodium. However, sodium ions are larger than lithium ions so that the anode materials of LIBs are not suitable for SIBs. Therefore, many negative electrode materials have been investigated. Among them, Sb2S3-based nanomaterials have gradually become a research focus due to their high theoretical specific capacity, good thermal stability, simple preparation, and low price. In this review, the research progress of Sb2S3-based nanomaterials in the SIB field in recent years is summarized, including Sb2S3, Sb2S3/carbon composites, Sb2S3/graphene composites, and Sb2S3/MxSy composites. Furthermore, the challenges and prospects for the development of Sb2S3-based nanomaterials are also put forward. We hope this review will contribute to the design and manufacture of high-performance SIBs and promote its practical application.

“…The strong chemical bonding of nanostructured Sb 2 S 3 on heteroatom-doped graphene or carbon matrix have been disclosed by electrochemical analysis as well as computational calculations [38,163]. It has been found that heteroatoms-doped graphene or carbon usually accounts for the improvement of electronic and ionic conductivity [164,165] or improve the adsorption of Sb 2 S 3 on the matrix [166,167]. Moreover, density function theory (DFT) calculation confirmed that the sulfur and Sb doped-carbon substrates increase the adsorption energies, charge transfer, specific capacities and the diffusion properties of Na + ions [168].…”

Sodium-ion batteries (SIBs) are considered a potential alternative to lithium-ion batteries (LIBs) for energy storage due to their low cost and the large abundance of sodium resources. The search for new anode materials for SIBs has become a vital approach to satisfying the ever-growing demands for better performance with higher energy/power densities, improved safety and a longer cycle life. Recently, antimony (Sb) has been extensively researched as a promising candidate due to its high specific capacity through an alloying/dealloying process. In this review article, we will focus on different categories of the emerging Sb based anode materials with distinct sodium storage mechanisms including Sb, two-dimensional antimonene and antimony chalcogenide (Sb2S3 and Sb2Se3). For each part, we emphasize that the novel construction of an advanced nanostructured anode with unique structures could effectively improve sodium storage properties. We also highlight that sodium storage capability can be enhanced through designing advanced nanocomposite materials containing Sb based materials and other carbonaceous modification or metal supports. Moreover, the recent advances in operando/in-situ investigation of its sodium storage mechanism are also summarized. By providing such a systematic probe, we aim to stress the significance of novel nanostructures and advanced compositing that would contribute to enhanced sodium storage performance, thus making Sb based materials as promising anodes for next-generation high-performance SIBs.
